You may need to check for a vacuum leak in the intake manifold and carb
connection. Been there - done that.

Subject: Same problem but different...Re: Electrical Question
Hello everyone,
I've been having a problem with my new B (1970 w/1974 motor/twin carb). It
seems that the front two cylinders don't want to work...the effect is a
jumping, missing motor. It'll run, but it really doen't have the power that
it is supposed to, and it keeps missing. Now...My first thought was to
replace the sparkplugs, and I did. I also checked the points, and they were
new. It didn't get better. I then looked for new sparkplug wires, but no
one had any. I ordered them yesterday and picked them up this morning.
However, yesterday, I went ahead and replaced the distributer cap along with
the rotor within the distributer. No difference. I also checked to make
sure the wires were in the correct firing order, and they were. We moved
the timing, and only a slight difference could be noticed. This morning I
finally got to replacing the wires, but there was still no difference. What
next? The carbeurator...so far I have partially ruled this out...1) the
plugs have had gas on them...2)while going down the road, I pulled the
choke, and there was no difference at all (thinking along the lines that if
one of the carbs was thirsting for fuel, the extra boost would help).
Now...as was related in Re: Electrical Question, I had already pulled the
front two plugs, and it didn't make any difference. Switched them
around...no difference. The second two do make it worse when you take them
off however.
What else is there to look at? Could it still be the front carb? Could a
valve be stuck somewhere? Is there something I missed in the electrical
system?
Anyway...any and all help will be most appreciated. :)
Thanks,
